Bobby Heenan -The Weasel reads
When fielded, until the end of the turn, for each die your opponent assigns to block they lose a life
Foetid Bloat Drone - Putrid Explosion reads
Deadly
When Foetid Bloat Drone attacks, all opposing character dice must block
If I field a Bobby Heenan die, then attack with a Foetid Bloat Drone die, would my opponent have to block with all his dice or would the life loss be considered a cost?
All other instances of can't Vs can specifically say in the ability 'can't block unless X is paid' but Bobby Heenan doesn't, therefore I feel the former is the case that all would have to block
